J. (-3.l BAUDINO PINoN NUT .SHELLER Filed May 24, 1928 2 Sheets-Sheet 2 Patented June 9, 1931 UNITED STATES JAMES G. BAUDINO, or ammonia, UTAH PINON NUT SHELLER Application mea May 24, 192s. seriiNo. 280,262.

This invention relates to a pinon nut sheller.

An important obj ect of the invention is the provision of a device for removing the shells 6 from pinon nuts which is of such character that the shells will be so broken that they may be readily separated from the nuts and, at the same time, a very low percentage of the nuts are crushed or otherwiserendered unfit for 10 use. j

A further object of the invention is to provide a device of this character which may be very readily and cheaply manufactured and which will be durable and efficient in service. A still further object of the invention is to provide a structure fr removing thin brittle shells from nuts including a rotating burr element and a stationary burr element between which the nuts are passed to rupture the shells thereof, the structure of the stationary burr element being such that a new surface may be quickly 2presented for service when, in use, the burrs of such stationary element become worn or are otherwise destroyed.

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a side elevation of a pinon nut sheller constructed in'accordance with my in- Y j Referring now more particularly to the longitudinal sectional Vview ards, 11 the side members and 12 the end membersof a frame. In accordance with my invention, I provide three parallel shafts 13, 14 and 15, which are mounted in bearings carried by the side members. The shaft 13 drawings, the numeral 10 indicates the stand-- is provided uponits opposite `ends with pul-` v leys 16V and 17` and has secured theretoA in-V wardlyhof the pulley17 a small gear 18. The I endof the, shaft with which the pulley16 is engaged is extended beyond this pulley and adapted, as at 19, for engagement with a handle,fwhereby it may be rotated. The vvshaft 14 has secured theretoA a gear 2O of greater size than andmeshing with the gear 18, so

that the shaft 14 willbe rotated ata slowerv rateof speedthan the shaft 13 when driven therefrom. Between its bearings,.thejshaft.V

14 has secured thereto a roll 2.1 to the periphery of 1which is secured a metallic sheet 22 having burrs 23upon theouter `face thereof formed by Vpunching `the sheet fromitsinner f face with a blunted instrument. Other means of producing'these burrs maybeemployed,

' shaft isprovided with circumferential series of spaced sockets 2G adapted toareceive kthe inner end of aset-screw 27 vdirected. through the encaslng bearing cap 28, so that this shaft` ifldesired.` TheY shaft lrhas secured theret.

may beheld against rotationin adjustedpositions. .i Secured to the side members 11 between the bearingsof the shafts 14 and 15 are feet 29 formed upon the lower lends of the vertical side walls 30 ofa hopper 31.V The'end walls of this hopper', indicated at 32, converge downwardly and have their lower endsinv close Vproximity to the upper surfaces ofthe rolls 21 and24 respectively.

l The mechanism just described is arranged at one end of the frame and beneath the frame at the opposite end thereof is disposed a separator 33 for separating nuts and the hulls thereof. The operating shaft 34 of this separator is provided with a pulley 35 aligning withand connected to the pulley 17 bya belt 36. VA chute is provided for leading the hulled n'uts and their hulls from the rolls21 and 24 tol this separater, this chute having an inclined bottom 37, the upper end of which is extended into close proximity to the lower surface of the roll 24. From this roll, the

i nu.. y

the vmaintenance of suliicient space lbetween Y the rolls, any crushing of the nuts themselves. is avoided. As the teeth of the operating section of the roll 24 become dulled or ineffective, a fresh working surface may be presented y by releasing the set-screws 27 and partiallyrotating the shaft and its roll. The nuts and their crushed hulls will Vbe vtlfeliver'edkto the chute 3 and from this'chute to the separator 33.v i 3 kSince the construction hereinbefore set'.

forth is capable of a certain range of changeA and modification without materially depart-fV l ing from the spirit of the invention, I do not limit myself to such specific structure except ashe'reinafter claimed.

Iclaimzwy f v f -In a nut sheller for pinon nuts and the likej a pairrofrolls, a removable covering for the rolls providingthe rolls with aburred periphery, vthe rolls having their adjacent 'faces spaced, a shaft upon which one of the rolls is mounted, bearings for said shaft, the shaft within one of the bearings having acircum ferential `'series 0f spaced sockets, a screw adjustable through the cap of the said one of thebearings for selective engagement in y said socketsto hold said shaft against'rotation and means for rotating the other of the rolls. v l 1 In testimony whereof I hereunto aX my signature.
